阅读下面一段程序: words = "Hello,Python" index = words.index("Py", 0,6) print(index) 运行程序,最终执行的结果为()
举一反三
- 阅读下面一段示例程序: demo_list = [] demo_list.append("A","B") print(demo_list) 运行程序,其最终执行的结果为
- 当输入为 ‘cbabc’ 时，下列程序的输出结果为？s1 = raw_input() index = 0 s2 = '' while index [ len(s1) - 1: if s1[index] ] s1[index + 1]: s2 += s1[index] else: s2 = s2 * 2 index += 1 print s2
- 写出下面程序的输出结果 publicclassTestjava{ publicstaticvoidmain(String[]args){ Stringstr="abbaefabbewbvwabbswgfga"; System.out.println("count="+getSubCount(str,"abb")); } publicstaticintgetSubCount(Stringstr,Stringkey){ intcount=0; intindex=0; while((index=str.indexOf(key,index))!=-1){ System.out.println("index="+index); index=index+key.length(); count++; } returncount; } }
- 阅读下面的程序，其时间复杂度为_________?1. int index =...009. index=index+2;
- score是一个整数数组，有五个元素，已经正确初始化并赋值，仔细阅读下面代码，程序运行结果是() temp = score[0]; for (int index = 1;index < 5;index++) { if (score[index] < temp) { temp = score[index]; } }
